A Direct-conversion Receiver for 5 GHz Wireless LAN with Sub-harmonic Down-conversion

This article describes a CMOS direct-conversion receiver for 5 GHz wireless LAN. Sub-harmonic mixing is used for down-conversion to minimize the DC-offset due to LO-leakage. The residual DC-offset is cancelled by a digital-to-analog converter at the ou...
Among the various kinds of wireless communication systems, wireless LAN (WLAN) is the most popular for short-range communications, due to its high data rate. For low cost and low power implementation of a WLAN terminal, a fully integrated CMOS RF transceiver is required for which a low- or zero-IF...
